1B) (Matson 1986). Polarity is ascertained by identifying the duplex region that is denatured by the helicase. For helicases involved in DNA replication, the polarity of the reaction is strongly indicative of helicase placement on the leading (a 3 ' -5 'polarity) or lagging (a 5 +3 'polarity) strand.NA HELICASE ASSAYS DNA helicases are often first detected by a DNA-dependent or DNA-stimulated NTPase activity. Verification of DNA helicase activity is then accomplished using an assay that reveals the conversion of double-stranded DNA (dsDNA) into two single strands.
1. typical enlistment is 4 years, however during Vietnam 3 year enlistments were allowed. 2. The 3rd Marine Division was reactivated for Korea, and in 1956 moved to Okinawa as the cease fire there looked like it would hold. Air Bases remained active in Okinawa during the entire postwar and Cold War era to date.
Throughout the Vietnam era, the median education level of the enlisted man was about 13 years. Proportionately, three times as many college graduates served in Vietnam than in WWII. Another common assumption: The war in Vietnam was fought by youngsters wet behind the ears, who died as teenagers barely old enough to shave. In fact, more 52-year-olds (22) died in Vietnam than 17-year-olds (12). An analysis of data from the Department of Defense shows the average age of men killed in Vietnam was 22.8 years, or almost 23 years old.
